I recently bought JAG by Entrek knives. It was on sale and $ 97.00 did not seem much. I inspected the knife closely and discovered that there was glue sticking out from under the scale. I decided to remove it. When I did it I found out that the blade under had totaly different finish.

Is the bead (sand) blasted finish done after the knife is assembled? And how.

Thanks for any info.

I do quite a bit of sand blasting and bead blasting. I use beads for the blade finish and silicon carbide for blast engraving my logos and personalizations. When I blast, in in the process of making the knife depends on the handle material. If its going to be all bead blasted with a macarta handle, I finish the knife then blast the whole thing. Sometimes I get a request for a bead blasted blade with a fancier polished handle and vise versa. Then I do the blade and the handle separately. With folders its easy because you can do all the individual parts, then assemble them. It sounds like they didn't clean all the glue off your knife before they blasted it. I have found spots like that on my knives, but I catch them at "Final Inspection" and re-blast! I am sure the company would take the knife back and shoot it again, its not that dificult!

DR. LATHE, can you please tell me what you use as a stencil material when you blast etch your logo onto a blade, and where I can buy some? Also, have you ever used this method to etch pictures on your blades? Thanks and take care! Michael
 
OOPS!!!!!!! I'm sorry, I meant blast engraving. Do you bead blast your blades before they are heat treated?? Thanks! Michael
 
L6,
I don't use a commercially available product! I mix and make a photo resist myself, that will stand up to sandblasting. The process I use is patented and is still used by my former partner in the glass engraving industry. He has no problem with me doing it on knives, however I agreed to keep the process to myself!
I would be glad to share any information on knife making that I possibly could. This is touchy subject that could interfere with my monthly checks from the sale of my business!
The pictures on my website dont' quite show the detail and depth of my logos. I have to get a close up lens!!

I understand your position Dr. You've given me a hint at an idea. I'll let everyone know if it works out. Take care everyone!! Michael
 
L6,
Before you get started, let me say this!!
I average about 1 hour per blade that I engrave with this process! Making, exposing and developing photoresist masking is not an easy process. Blowing through the resist on a polished knife blade can cause one to use foul language!!! HOWEVER... The results cannot be equalled by any other process!!
Let me know how you make out,
Neil Blackwood
